SLOT SEALING COMPOUND, SLOT SEAL, AND METHOD FOR PRODUCING A SLOT SEAL

摘要

The invention relates to a slot sealing compound (7) for an electrical machine that comprises at least one slot (2) with a slot opening (5) for receiving an electrical conductor arrangement (3). Said slot sealing compound (7) contains a magnetic filler material, particularly a soft-magnetic filler material, and a reactive resin mixture that comprises at least one resin component. In the interests of improving storage stability for said slot sealing compound (7), the components thereof are selected to be suitable for cationic polymerisation. A catalyst, provided to accelerate the cationic polymerisation of said reactive resin mixture, is also added to said slot sealing compound (7).
